Hi all.

Anyone ever figured out why Windows updates fail when the computer has
an IPv6 connection?

Weird .. We have PC running Windows 10 pro (20+) in my organization
(based in Cameroon) and dont have that issue.

I have a family PC at home running Windows 10 Pro, and noticed updates
would fail in recent months. It took me a moment to realize that this
started happening only after I enabled IPv6 in the TCP/IP stack.
Disabling it immediately solves the issue.

Quite odd that this is happening in 2018...

IMHO the issue is in the network somewhere ...
